You should real read through the post before commenting. I hate when people do this! There already is a member on here who made 620hp with e85 on 4 1000cc injectors and the injectors are only at 90% duty cycle.

 

E85 A/F is run at around 12.5:1-12.8:1 on boosted applications as apposed to 11.5:1-11.8:1 with gas or race fuel. Meaning you can run it quite a bit leaner.

 

the air fuels you quote are for gas.. stoich for e85 is 9.7:1.

if you use a standard air fuel gauge that displays gas afr's you would want to shoot for around 10.5:1-11:1, thats 0.7ish lambda

for an NA car, around 12.5 or so is what you would look for

 

Not according to the big EVO guys that make big power on e85. They, along with my friend/tuner that has an 800 whp AMS built EVO runs his at 12.5:1 A/F reading off his wideband and I've seen it first hand.

 

then the blend they use must not be e85. i have tuned alot of cars with all sorts of fuels and gas is almost always the "leanest"

those 800hp t3 turbo'd evo's dont really follow the "rules" anyway.. lol

alot of e85 is really e70, which you could probably get away with running that lean.

 

This is True at red line i am at 12.5 afr and right around 12 every where else. E85 is run leaner then gas.

"Is that 90 psi of fuel pressure at full boost? Can you tell us what you have your idle fuel pressure set at?" I would have to double check this but yes i believe at red line or at least close but like i said not 100% sure. The car is in storage now so i will not be able to get to it. I will talk to my tuner and see if he remembers.

I also never added The injectors are maxed out at this level I will be going to the ID2000cc ones next year and see how much they are good for.

Also Remember peter at ISP has made 730whp on E85 Twin walbro's and 1600cc's on a 6262.

 

Thanks for confirming that man. I knew you could run e85 leaner.

As for the ID2200's, ill be going with those in the near future also. I'm just going to wait a bit to see if the price of them drops and go ahead for now and max out my rc1000's at a higher fuel pressure like you did. I hope to get around 600 whp out of them. That will be great if you can get that info as to where you have your idle fuel pressure set at. Ill be installing the FB dual pump setup in about a week so ill have plenty of fuel flow for this.

 

STL2SLW what boost levels did it take to achieve those numbers?

 

I am running right around 21-21.5 psi at full boost.

 

I know this is an old thread but spoolin how many whp did u put down? I'm getting my setup returned this Wednesday single fbm 340 pump Id1000 e85.
